Filter by:Fetuin-A has been identified as a novel physiological regulator of insulin action in vitro, in intact cells and in vivo in animals. Previous research has shown that circulating levels of fetuin-A were increased in animal models of insulin resistance and diabetes. Additionally, several human investigation studies demonstrate a correlation of fetuin-A levels with body mass index, insulin resistance, and a fatty liver. Recently, the investigators have elucidated the role of fetuin-A phosphorylation in the regulation of insulin action, demonstrating that phosphorylation is critical for the inhibitory activity of fetuin-A. The objectives of this study are twofold: (1) Quantitate phosphorylated fetuin-A levels in individuals with insulin resistance and metabolic syndrome, and (2) Investigate the effects of lifestyle modifications (acute or chronic exercise and dietary modifications) on fetuin-A phosphorylation and insulin sensitivity.
Obesity is increasing in western society at a rapid rate and is associated with metabolic and cardiovascular disease. Although genetics, improper diet, and sedentary lifestyle are known to be factors that can cause obesity, there is a new idea that certain gut microbes may also be involved. Patients who are obese tend to have different kinds of gut microbes compared with lean healthy individuals. Previous studies have shown that changing the gut microbes of obese individuals by doing a fecal transplant (FMT) using gut microbes from a lean individual improves insulin resistance. However, the effects were not maintained. In addition, research has highlighted a necessary role for dietary fiber in the maintenance of microbes required for human health and also that increasing dietary fiber can reduce inflammation that is associated with insulin resistance. This project builds on the findings that gut microbes can be modulated by both FMT and dietary fiber supplementation and will examine if combining these two treatments can increase the effectiveness of these treatments. The objective of this study is to use fecal microbial transplant to change the gut microbes of obese individuals to those seen in lean individuals and then to use fiber supplements to help maintain the beneficial effects. In this study, overweight individuals who have metabolic syndrome will receive a fecal transplant using a pill form and then consume a variety of fiber supplements for 6 weeks. Effects on metabolic parameters, quality of life, weight, and dietary intake will be followed. Microbial composition will be measured in stool samples.
The purpose of the study to assess the efficacy of adding L-carnitine to clomiphene citrate for increasing the ovulation and the pregnancy rate in women with PCOS.
Specific Aim #1 (Feasibility; primary aim): To assess the feasibility of the positive psychology (PP)-motivational interviewing (MI) group-based physical activity intervention and outcome assessments in patients with metabolic syndrome (MetS). Hypothesis: The PP exercises and MI-based goal-setting sessions will be feasible: most (≥50%) of participants will complete 6/8 exercises/sessions. Furthermore, we will be able to obtain objective physical activity measurement follow-up data from at least 80% of enrolled participants at 8 weeks. Specific Aim #2 (Acceptability): To assess whether the intervention is acceptable to participants, as measured by ratings provided after each PP and MI exercise. Hypothesis: The intervention will be acceptable: participants will rate each PP and MI exercise with a mean score of at least 7 out of 10 on ratings of ease of completion and helpfulness. Specific Aim #3 (Outcomes): To assess whether this preliminary intervention appears to result in improvement of physical activity, related health behaviors (sedentary time, diet quality), and psychological well-being (optimism, positive affect, anxiety, depression). Hypothesis: The intervention will lead to improvements in physical activity, related health behaviors, optimism and positive affect, and reductions in depression and anxiety at 8 weeks compared to baseline.
This is a phase 3, multicenter, double-blind, randomized, placebo-controlled, parallel-group study to evaluate the efficacy and safety of CSL112 on reducing the risk of major adverse CV events [MACE - cardiovascular (CV) death, myocardial infarction (MI), and stroke] in subjects with acute coronary syndrome (ACS) diagnosed with either ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI), including those managed with percutaneous coronary intervention (PCI) or medically managed.
The objective of this study is to evaluate the long-term safety and efficacy of linaclotide in post-marketing use.
Post-operative paediatric cerebellar mutism syndrome (pCMS) is a well-recognised complication of resective surgery for brain tumours of the cerebellum and fourth ventricle in children. Occurring in around 25% of infratentorial craniotomies, it is characterised by a delayed onset of mutism and emotional lability, and may comprise motoric and cognitive cerebellar deficits. Transient mutism gives way to prolonged, and often incomplete, recovery. Neuroimaging studies are beginning to reveal anatomical and functional aberrancies in the brain of children with pCMS. The cerebellar efferent pathways are likely to be implicated as a neuroanatomical substrate in the development of pCMS, as shown by a handful of diffusion tractography studies to date. However, the pathophysiology of this condition still remains unclear. Hypoperfusion of supratentorial cortical and subcortical structures may mediate the speech and behavioural deficits seen in pCMS, and is a candidate for a causal pathophysiological mechanism. This study aims to prospectively image children with pCMS using advanced MRI techniques including diffusion tractography and arterial spin labelling, and to correlate this with clinical descriptions of the syndrome. All children referred to Great Ormond Street Hospital for Children with a posterior fossa brain tumour will be imaged pre-operatively, post-operatively and at delayed follow-up. In tandem with this, clinical assessments will be made of children post-operatively to ascertain which patients develop pCMS. In addition, anonymised advanced MRI data on healthy controls will be used as a comparator group.
Posterior Reversible Encephalopathy Syndrome prospective (PRES) registry. Data collection using a standardized form : demographic data and data related to the PRES, including circumstances of onset, dates and times of onset and of symptoms control, on-scene clinical findings, clinical and radiological features of PRES, pre-hospital and hospital care providers, timing of antiepileptic, antihypertensive drugs and supportive treatments, results of etiological investigations, cause of PRES, type and dosage of antiepileptic and antihypertensive drugs. Dates and times of EEG monitoring, EEG results, radiological and biological investigations. Outcomes including vital status and Glasgow Outcome Scale score at ICU and hospital discharge, day-90 and 1-year after SE and determined based on data in the ICU and/or neurologist charts and/or patients phone interview
Cyclic vomiting syndrome is a disorder characterized by nausea and vomiting, separated by periods without any symptoms. There is very little research on this field at this point and most doctors do not fully understand the disorder. The goal of this study is to assess how the stomach empties food. Participants will be asked to participate in this study because either (a) they have been diagnosed and/or treated for cyclic vomiting syndrome in the past, or (b) they are physically healthy. The study seeks to compare how a healthy person's stomach empties to how the stomach of someone with cyclic vomiting disorder empties.
Current diagnostic criteria for Immune ThrombocytoPenia (ITP) are mainly based on the presence of low numbers of platelets, excluding other multiple causes of thrombocytopenia, including immunodeficiencies, constitutional or acquired thrombocytopenia, hypersplenism and clonal hematological disorders such as MDS, disorders lymphoproliferative and acute myeloid leukemia (AML), among others. The analysis complementary tests for the diagnosis of ITP include studies basic systematic hematology, together with autoimmune assays and microbiological tests, while the evaluation of bone marrow is limited to elderly patients and/or patients resistant to treatment. Previous research has described the development of Myelodysplastic Syndrome (MDS) in patients with a previous diagnosis of ITP, and even the presence of MDS associated with genetic background. Therefore, it is conceivable fact that a percentage of cases with clinical signs of ITP in the moment of appearance may actually correspond to the first stages of MDS development in which bone marrow cells are not systematically evaluated in the initial presentation. The anomalous immunophenotypic patterns between multiple compartments of bone marrow cells and peripherally blood (PB) platelets have been characterized through flow cytometry. The flow cytometry currently represents an important complementary tool for diagnosis of MDS that has shown great effectiveness and applicability in the differential diagnosis of non-clonal cytopenias against early MDS and for the detection of stages prior to MDS. Besides, the flow cytometry has made it possible to detect the presence of coexisting features related to MDS in patients with other malignancies hematologic conditions such as multiple myeloma, AML, and lymphocytic leukemia chronic. Therefore, the immunophenotypic analysis of the cells of the bone marrow of patients with ITP at the time of appearance would help to identify the cases that underlie clonal hematopoiesis MDS type. In the present study it is planned a broad characterization immunophenotyping of multiple compartments of bone marrow cells and PB platelets from patients with recently diagnosed ITP and investigate their morphological antecedents, in order to identify those patients who show compatible clonal hematopoietic patterns with MDS evident (or at risk of development), as candidates to receive most appropriate therapeutic methods.
